Antoine Pitrou commented on ARROW-14089:
----------------------------------------
Are such files still around? Otherwise we may not bother and spend development
time on more useful tasks :)
> [C++] Read DELTA_BYTE_ARRAY data written with bug PARQUET-246
> -------------------------------------------------------------
>
> Key: ARROW-14089
> URL: https://issues.apache.org/jira/browse/ARROW-14089
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Shan Huang
> Priority: Major
>
> If a parquet file is written by parquet-mr before version 1.8.0, the bug
> [PARQUET-246|https://issues.apache.org/jira/browse/PARQUET-246] will produce
> data inconsistent with the encoding of DELTA_BYTE_ARRAY.
> There are two solutions:
> 1. We should update the read side to recover data written with this bug.
> 2. We need to throw an exception if the parquet file is written by parquet-mr
> before version 1.8.0 and has DELTA_BYTE_ARRAY encoding data.
